Anyone tried GPT-4.5 yet? How's it going?

It sounds like GPT-4.5 got some cool upgrades. Just wondering if anyone here has had a chance to try it? How’s it performing for you? Is it noticeably better than GPT-4, especially with things like accuracy or handling more complex stuff?

I also saw that it’s only available for ChatGPT Pro users, and the price is pretty steep. I’m even using a shared account for ChatGPT Plus because of the cost.

Would love to hear what you all think if you’ve given it a go!
